Calibrachoa plant named ‘Docalhusopin 19’

ABSTRACT

A new and distinct cultivar of Calibrachoa plant named ‘Docalhusopin 19’, characterized by its semi-upright to outwardly spreading, trailing and decumbent plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; large flowers with light red purple-colored petals with dark red purple-colored centers; and good garden performance.

Botanical designation: Calibrachoa X hybrida.

Cultivar denomination: ‘DOCALHUSOPIN 19’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa X hybrida and hereinafter referred to by the name ‘Docalhusopin 19’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new freely branching and early-flowering Calibrachoa plants with numerous attractive flowers.

The new Calibrachoa plant originated from a cross-pollination made by the Inventor in July, 2016 in Rheinberg, Germany of a proprietary selection of Calibrachoa X hybrida identified as code number AA15-005956-002, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa X hybrida identified as code number AA14-007028-003, not patented, as the male, or pollen, parent. The new Calibrachoa plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2018.

Asexual reproduction of the new Calibrachoa plant by vegetative terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2018 has shown that the unique features of this new Calibrachoa plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Docalhusopin 19’. These characteristics in combination distinguish ‘Docalhusopin 19’ as a new and distinct Calibrachoa plant:

-   -   1. Semi-upright to outwardly spreading, trailing and decumbent         plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Early and freely flowering habit.     -   5. Large flowers with light red purple-colored petals with dark         red purple-colored centers.     -   6. Good garden performance.

The new Calibrachoa can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa have larger flowers than plants         of the female parent selection.     -   2. Flowers of plants of the new Calibrachoa are lighter red         purple in color than flowers of plants of the female parent         selection.

The new Calibrachoa can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa have larger flowers than plants         of the male parent selection.     -   2. Flowers of plants of the new Calibrachoa are light red purple         and dark red purple in color whereas flowers of plants of the         male parent selection have red-colored flowers.

Plants of the new Calibrachoa can be compared to plants of Calibrachoa sp. ‘Mini Famous Red+Pink Eye’, not patented. In side-by-side comparisons, plants of the new Calibrachoa differ primarily from plants of ‘Mini Famous Red+Pink Eye’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa have thicker lateral branches         than plants of ‘Mini Famous Red+Pink Eye’.     -   2. Plants of the new Calibrachoa have longer and darker         green-colored leaves than plants of ‘Mini Famous Red+Pink Eye’.     -   3. Plants of the new Calibrachoa are more freely flowering than         plants of ‘Mini Famous Red+Pink Eye’.     -   4. Plants of the new Calibrachoa have larger flowers than plants         of ‘Mini Famous Red+Pink Eye’.     -   5. Plants of the new Calibrachoa and ‘Mini Famous Red+Pink Eye’         differ in flower color as plants of ‘Mini Famous Red+Pink Eye’         have lighter-colored flowers.     -   6. Plants of the new Calibrachoa have larger sepals than plants         of ‘Mini Famous Red+Pink Eye’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Calibrachoa plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Calibrachoa plant.

The photograph on the first sheet (FIG. 1 of 2) is a side perspective view of a typical flowering plant of ‘Docalhusopin 19’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring in 13-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Calibrachoa production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 1,500 lux. Rooted young plants were pinched one time three weeks after planting and were twelve weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
